According to the app I’m 8wks 2 days today. Starting yesterday my lower back has been aching so bad. It seems muscular because if I sit perfectly still it goes away. But the second I stand up or bend over it hurts so bad. This is my third pregnancy, and will be my 2nd baby. I have a 3 year old son and I don’t remember having this when I was pregnant with him. Can anyone relate? I lost my 2nd pregnancy at 11wks 1 day so every twinge I feel makes me so nervous. Just wondering if this is normal or not as it seems early on to be having back pain.
